chuanzhen

Hi,
i use this script code to detect obj selected in InExcludeData(),always return "None"

import c4d

doc: c4d.documents.BaseDocument  # The currently active document.
op: c4d.BaseObject | None  # The primary selected object in `doc`. Can be `None`.

def main() -> None:
    ie = op[c4d.ID_USERDATA,1]
    for i in range(ie.GetObjectCount()):
        print(ie.GetData(i)[c4d.IN_EXCLUDE_DATA_SELECTION])

if __name__ == '__main__':
    main()

i found a example code in this post,but it also not work.

Thanks for any help!

Hey @chuanzhen,

Thank you for reaching out to us. For me this works fine, but I also struggled for a second with this. The crucial information is probably that you have to set SEND_SELCHNGMSG in the InExcludeCustomGui for which this shall work. Since this information is rather obscure, I have updated the docs of InExcludeData::GetData to better reflect this.

Cheers,
Ferdinand

Supplement an example of generating UserData using code:

import c4d


def main() -> None:
    
    
    bc = c4d.GetCustomDataTypeDefault(c4d.CUSTOMDATATYPE_INEXCLUDE_LIST)
    bc[c4d.DESC_NAME] = "Test"
    bc[c4d.IN_EXCLUDE_FLAG_SEND_SELCHANGE_MSG] = True
    did = op.AddUserData(bc)
    c4d.EventAdd()

if __name__ == '__main__':
    main()
